“…Moreover, interferometers with high spectral sensitivity are becoming more and more desired in applications such as metrology, 5 optical sensing, 6 quantum information processing, 7 and biomedical engineering. 8 A number of schemes have been proposed to enhance the performance of interferometers, such as using PhC structures to minimize the size of on-chip devices 9 and electromagnetically induced transparency to increase the rotation sensitivity of a Sagnac interferometer.…”

Public reporting burden for the collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. We demonstrate experimentally that the spectral sensitivity of an interferometer can be greatly enhanced by introducing a slow-light medium into it. The experimental results agree very well with theoretical predictions that the enhancement factor of the spectral sensitivity is equal to the group index n g of the slow-light medium.

“…Using multiple 40 GHz phase modulations of a CW laser, MSTAR [6] has reached nm-scale accuracy. More recently Coddington et al [7] have demonstrated a laser ranging scheme that efficiently combines time-of-flight and interference measurements in a single measurement inspired from optical linear sampling [8].…”

-We present a laser ranging system, under development, that uses a high frequency modulated beam to achieve sub-nm resolution by the combined use of interferometric and time-of-flight measurements. We first describe how the absolute distance is extracted from a two-mode interference signal. In particular we show that the signal, which presents both optical and synthetic wavelength scales, is essential to achieve nm-scale accuracy, despite the significant long-term phase drifts in the 20 GHz detection chains. Then we present results obtained with the telemeter implemented on an optical table, for a distance of about four meters, implemented by folding the laser beam path to the target. The challenge here is to achieve a phase and amplitude measurement of two 20 GHz signals with a resolution well below 10 -4 cycle and 10 -4 , respectively, despite the fact that the signal undergoes very strong ( 3 × ) amplitude changes.

“…Devices with large spectral sensitivity are becoming increasingly desirable in applications such as metrology, optical sensing, quantum information processing, and biomedical engineering [1][2][3][4]. Although the spectral sensitivity can be enhanced using slow light [5,6], the central measurement is usually that of the optical phase, and therefore requires the use of an interferometer.…”
